Exodus 26:26-30

“And you shall make bars of acacia wood: five for the boards on one side of the tabernacle, five bars for the boards on the other side of the tabernacle, and five bars for the boards of the side of the tabernacle, for the far side westward. The middle bar shall pass through the midst of the boards from end to end. You shall overlay the boards with gold, make their rings of gold as holders for the bars, and overlay the bars with gold. And you shall raise up the tabernacle according to its pattern which you were shown on the mountain.
